JOHN A. KEssEL, or U F LO, NEW. YORK.

To all whom it mag concern. I

Be it known that I, JOHNA. KESSEL, a citizen of the UnitedStates,cresiding at Buffalo, in the county of Erie and State .of NewYork, have invented new" and useful Improvements in Ash-Sifters, ofwhich the following is a specification.

This invention relates toanash sifter which permits of sifting asheswithout permitting dust to escape to the surrounding atmosphere as is.commonly. the case in ash sifters as heretofore constructed. It is the'object of this invention to produce a sifter of this character which'issimple and inexpensive in construction, which can be'easily operated,and which permits of conveniently separating the dust and clinkersfrom'the good coal without removing the sieve from the sifting chamberand thereby render the sifting operation cleanly, and agreeable.

In the accompanying drawings:

Figure 1 is a perspective view showing one form of ash sifterembodyingmy invention. Fig. 2 is a vertical section ofv the same takenon line 2-2, Fig. 3. Fig.3 is a horizontal section taken on line 33,Fig. 2. Fig. 4 is a fragmentary vertical section taken on line4-4, 3.Figs. 5'and .6

are perspective views of the two sections of the sieve forming part ofmy invention. Fig. '7 is a similar view of a scoop for use in placingthe ashesto be sifted intothe sieve within the sifting chamber. Fig. 8is a vertical section ,of an ash siftershowing my improvements in aslightly different form from that shown in Figs. 1 and 2.

Similar characters of referenceindicate corresponding parts throughoutthe several views. In the form of my invention shown in Figs. 1 and 2',the sifting chamber is formed within an inclosing casing whichpreferably comprises an upright cylindrical wall 1 havingan open top,and a cover 2 adapted to close this top, both of these members beingpreferably constructed of sheetmetal in any suitable manner. The outerside of the sifting chamber may be provided with handles 1 for carryingthe same and the ,cover may be providedwithahandle 2 for liftingW'ithinv the lower part of this Slftlllg.

or rim 4 whichrests with itsunderside on the supporting lugs 3 and apartition 5 extending across the space within the sieve frame on oneside of its center or axis of rotation so as to form two compartments inthis frame one of which is comparatively large and the othercomparatively small. A large main screen section 6 is permanentlysecured to the lower end of the large com .partment of the sieve frameand a small auxiliary screen section 7 is removably arranged in thesmall compartment, of the sieve frame and adapted to rest on lugs orshoulders 8 formed on thesieve frame within the small compartmentthereof. If 'de sired the'small; sieve "section may be pro- 1 vided witha rim 9 for stiffening the same and also with a handle 10 securedcentrally to its uppersidefor the purpose of removing it from the sieveframe when required.-

The sieve as a whole may be introduced into the sifting chamber from itstop and also removed therefrom by means of handles 11, llxsecured to theperipheral wall thereof on its-diametrically opposite sides, as shown inFigs. 2. 3 and 6- The-horizontally oscillating or shaking movement isimpartedto the sieve by means of ahandle 12'projecting througha:horizontal slot 13 in the side wall of the sifting chamber andconnectedat its inner end to :the main frame or wall of the sieve. Thishandle is made detachable from the sieve frame in order to 'permit'thelatter to'be removed from the sifting chamber for dumping 'the good coalout of the sieve. This detachable connection may be constructed invarious :ways, for instance, by providing the inner end of the shakerhandle with an externally screw threaded shank 14 engaging with a screwthreaded opening or socket 15 in the wall of the sieve frame, as shownin-Figs. 3, 4 and 6. Upon shaking the sieve the dustpasses downwardlyfrom the underside thereof while the large particles, such as the goodcoal and clinkers, are retained within the main and auxiliary sievesections. In order to permit of conveniently removing the clinkers fromthe good duces a flattening on one side of the main sieve section whichprovides the necessary passage through which the chnkers may be removedfrom the good coal and thrown into the dust pile below withoutnecessitating removing the sieve from the sifting chamber. 1

Means are provided whereby the ashes to be sifted may be introduced intothe sitting chamber and deposited within the sieve without producing anyappreciable dust outside of the sitting apparatus. For this purpose thesitting chamber is provided on one side of its wall with a laterally projecting hood 16 which is preferably of rectangular form and provided atits outer end with an ash inlet opening 17. This opening is surroundedby a flange 18 which inclines from its upper end inwardly toward itslower end so as to form a seat 19 on the inner side of this flange whichis adapted to be engaged by a vertically swinging gate, valve or shutter20. This shutter is pivoted at its upper end on the inner side of thehood, as shown at 21 and is held normally by gravity in its closedposition against the seat around the inlet of the hood.

The ashes are preferably removed from the ash pit of a furnace, stove orother place and passed through the inlet of the sitting chamber anddeposited upon the sieve there in by means of a scoop 22 which is ofcylindrical form and provided with'an inclined front end and the handle23 at its rear end. As the front end of this scoop enters the inlet ofthe sifting chamber it engages with the shutter and pushes the sameinwardly into an open position, as indicated by dotted lines in Fig. 2,and upon withdrawing this scoop after depositing the ashes on the sievethe weight of the shutter automatically returns the same to its closedposition, as incheated by full lines in Fig. 2, thereby effectivelypreventing the escape of any dust from the interior of the siftingchamber to the surrounding atmosphere.

During the operation ofsiftin the ashes there is no tendency of any ofthe dust to escape through the slot 13 in the side wall of the siftingchamber because there is no air current through this opening and for thefurther reason that this slot is practically covered by the annularframe of the sieve, as shown in Figs. 1, 3 and 4.

As the dust drops from the underside of the sieve the same may be takencare of in any suitable mannerand received either in a reit'usereceptacle or can 24 which is separate from. the sitting apparatusproper, as

I shown inl igs. 1 and 2, or in a receptacle 25 which is formed in onepiece with the wall 8. \Vhen the sitting chamber is made separate fromthe refuse receptacle the lower endiof the wall of the sitting chamberis provided with an annular base flange 27 whereby the same may resteither uponthe ground or floor when the sitting apparatus is not in use,or the samemay rest upon the upper edge of and form a tight joint withan Lash receptacle which is of the proper size 2G of the siftingchamber, as shown in Fig.

to fit the lower edge of the base flange, as

shown in Fig. 2. V

Inorder', however, to permit this sifting apparatus to be used inconnection with ash cans or refuse receptacles which are of smallerdiameter the interior of the sitting chamber is provided below the sievewith a downwardlytapering conical guide 28 which latter may be supportedwith its underside on the upper edge of an ash can or receptacle ofsmaller diameter, such' a can 29 being shown by dotted lines in Fig. 2.The baseflange of the sifter' preferably extends downwardly below thelower end of theguide 28 so that the latter will not be injured when thebase flange rests 'on the floor. By this'construction of ash sitter thesame may be used in connection with any available can or receptacle forreceiving the dust and clinkers and the same may be removed therefrombefore the ash man carts away the can, thereby avoiding injury to theash sitter, i

lVhen the ash receptacle is made in one piece with the sifting chamber,as shown in Fig. 8, the ashes may be removed therefrom into anotherreceptacle which is to be handled by the ash man in order to avoiddamage to the sitting apparatus.

Owing to the dust resulting from this sifting operation being positivelyconfined A within the sifting chamber in this apparatus it permits thisoperation to be performed in the basement or other available place of abuilding without causing any objectionable spreading of dust into thesurrounding space, thereby rendering the operation of sifting the ashesmore sanitary, pleasant and convenient. l

Moreover, this ash sitter has no delicate parts which are liable to getout of order andowing to the simplicity of its construction the same canbe produced at comparatively low cost.

I claim as my invention:

1. An ash sifter comprising a cylindrical siftingchamber having its axisarranged vertically and provided with internal supports, and a circularsieve adapted to rest sifting chamber havingits axis arranged verticallyand provided Withinternalsupports, and a circular sieve adapted to reston said supports and to'oscillate horizontally thereon and having alarge main section and a small auxiliary section; the division betweensaid sections being on one side of the center of the'axis of the sieve.

3. An ash sifter comprising a sifting.

chamber containing an internal support, and a sieve engaging saidsupport and'having a frame, a main screen section permanently connectedwith said frame, andan auxiliary screen section detachably mounted onsaid frame.

4. An ash sifter comprising'a sifting chamber containing an internalsupport, and asleve engaging sald support and having a frame, 'acomparatively large screen section permanently connected With saidframe, and
